When I boot the pi, I see the MagicMirror boot screen, the desktop, and then MagicMirror boots. Following the steps above did not solve the problem. Is the desktop supposed to show up before MagicMirror boots, or is it supposed to go straight into MagicMirror? After I see the boot screen and right before I see the desktop, it briefly becomes a black screen with an X in the upper left corner of the screen. Any ideas on what might be wrong? I have pm2 installed and it is functioning perfectly.
